To aZZ whom it may concern:

Be it known that 1, CHARLES F. P AsE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful Improvements in Continuous Blue-Printing, Washing, and Drying Apparatus, of which the following is a specification.

This invention relates to printing and developing blueprints, and pertains especially to an apparatus for printing, washing, and drying prints upon a continuous sheet or length of traveling paper.

ingthe paper after the prints have been made The subject-matter of this application is shown and described in connection with certain features. covered by my Patents No. 786,596 and No. 797,010. In the production of blue-prints upon a continuous traveling sheet either from separate short sheets of tracing or from continuous tracings it is highly essential to the avoidance of loss in sensitized surface, waste of material, stoppage of the traveling sheet, and the manipulation of the tracing and said sheet through the printer, as well as the disposition of the sheet for drying and the final disposition of the completed prints, that said operations be automatic and made to occur simultaneously and without interru tion. It is therefore the purpose of this invention to provide for the'printing, washing, and drying of continuous sheets of blue-print or other sensitized paper during the movement of the paper its entire length or any part thereof.

The object of the invention is to provide an apparatus for automatically printing, washing, drying, and rerolling blue-prints in a continuous traveling sheet or length of sensitized paper while the latter is in motion.

A further object of the invention is to provide a pair of washing and drying machines operated in connection with a printer for blue-printing separate and independent blueprint sheets or continuous lengths of sensitized paper while traveling in opposite directions by one and the same electric or other suitable light.

I The object, still further, of the invention is to provide in a blue-printing, washing, and drying apparatus a special device for rerollor fixed and the paper dried and to arrange such connections and'power transmission hetween the printer, the washer, and the rerollof the whole apparatus during the'entire length of the sensitized paper being operated I 1113011. j

In the accompanying drawings, forming part of this application, Figure-1 is a side ele- 6o vation, partly in section, showing a double apparatus constructed in accordance with i this invention. Fig. 2 is a sectional view showing course of paper through the washer and ClIiGI. Fig. 3 is a front elevation of the washer and drier. Fig. 4 is a detail side elevation of the rerolling device. Figf 5 is an elevation of the rerolling device looking i11 the direction'indicated by the arrow A. Fig.

6 is a detail elevation of a pair of tray-rollers. Fig. 7 is a front elevation of the tray-basin, partly broken away. Fig. 8 is a section on the line a as, Fig. 7, with paper therein. Fig. 9 9 is a perspective view of the rack. Fig. 10is a sectional view of part of an apparatus, showing a modification. Fig. 11 is a detail side elevation of certain driving pulleys and.- belts used in connection with the apparatus shown in Fig. 7.

The same reference-numerals dcnotethe same parts throughout the several views of the drawings.

The printer forms no part of, my invention and may be single or double, as desired, and when the latter is used the washer, drier, and rerolling device are duplicated, as shown in Fig. 1 of the drawings. 'lherei'ore a single apparatus will be herein described.

The printing-frame 1 is suitably fixed to a floor and has two .pairs of rollers 2, which feed the sensitized paper 3 from a roll 4 of said paper over a table 5, together with a tracing-sheet 6, through the path of'an electric light 7, where the tracing is caught in a 4 box 8, while the printingpaper is directed 5 over the edge of the'box and under the floor onto a carrier 9, composed of a seriesof ei d-' less tapes 10 and a pair of rollers L1; endless apron or wide belt would answer the same purpose as the tapes, or the paper could loo be dragged from the printer to the washer in the absence of the carrier, the object of thelatter being to support and carry all slack in the paper to a point under the washer wittiout danger of tearing the paper, the carrier having slightly greater speed than the paper.

The frame 1 has a shaft 12, which operates the rollers 2 and is adapted to be driven by any suitable power, preferably an electric, motor, (not shown,) and said shaft 12 has a eeeeet pulley 13, over which end thetepe-rollers l1 an endless belt 15 is operated.

An upright frame 16 carries the washing, drying, and rerolling devices mid-hes e ouli ley 1'], driven by the endless belt 15. Mo-

tion is imparted to e sprockebchein 18 by a smell pulley 19 on the spindle of the pulley 17, which pulley 19 operates on endless belt 20, rimming over a; pulley 21 on themeiiil' 'ro' shaft 22, Which has at sprocketevheel 23 for the chain 18. The ehsin operates e feed roller 2, joureelediti the top of the frame 16 mid he e, sprocketwheel 25 for the The basin 2690f the'washing tray 26 is pro- I titled with e reek composed of motel strips 122, spliced apart nearly the width of the basin, so as to permit the water to drip over the edges of vthe paper between the sides of ,zo the reel; mid the sides of the basin-into the 1 letter, This rack is hung in the basin 26 finders, roller 28. A roller 29 is placed over I {thefrorit edge oi. the basin, and a, series of "-rGllersBG are arranged end to end in the tray rind etjenengle lengthwise one to the other 11 ptfirefortl'le purpose of keeping the blueriritpeper stretched smoothly crosswise. fheigollei 28 ere vents the paper being lli'ted [out the basin, and the rack supports the fait the top of the tmy 26 is a sprevplpe 31,

; a id above this pipe is e roller 32, over and against which the paper travels. A. gas,

3 5- electric,-or steam heater 33 is secured to and central of the upright frame 16 above the tray for dryingcut the prints as the paper passes without contact with the heater to the 'rerollin device.

4o The evice for rerolling the Apeper consists of aseries of vertically-dis ose endlesstepes 34,0pereted by upper am lower roller-shefts 35; and 36, respectively, at roller 88, interposed in the path of the tapes 34, and a series 5 ,ofljeri'dless tapes 39, which are opereted over a 'roller 40, supported at an; angle to the tapes 34 by a, bracket 41, said tapes 39 being operetedfby the roller-shaft 3 6, which is provided, with a sheave 4.2, driven by e belt 43 The i'oller'38is revolved by a. crossbelt to-from the roller sheft36. it is obvious that the i'eifolling of thepeper roey be reversed, if do sired", by simply crossin the belt 3'7.

5 Referring to the modification shown in Fig".

, .10' of the drawings, a light-reflector 46 stands upon the to; of e box 47', having a platform v 48,, provide with a guard or shield 49. The .box' Mime a partition 50, forming a tracingreceptacleol, and the, top edge 52 of the partition '5'Qforms e, separator for the tracing 53 and printin =peper54. 8 One end of the box 17 is ettec ed to the washing-tray with .j 'the g'uerd 49overhanging the tray, and the peper 'd'rewr from said point of separation along the bottom of the box 427 to the tray. 'l'he receptacle 51 is provided with a, hinged lid 55 to expedite removel of the tracings.

. As further shown in Fig. 10, thereere three tlisngulerlyerrenged rollers 56, 56,

end 56 iii connection with c cutting-table 57, from which depends a casing 58, inelosing a suitable heater? 59, whioh mey be located Within or, as shown, supported on, the outside of the triangle from it floor edie'cent the lower roller 56 of the said three reliefs. The paper is drawn from the weehing-trey over a seller, (similer to thel'eede'oller 2t oi the preierred form of meehiee,} thence over the roller 5.6, then under the roller 56* by weyfof the lies-tier without contact therewith, end over the roller 55* to the table 57, where the p'epermey he out into sueh. lengths as they be As shown in Fig. ll, two of the rollers 56 and 56" are free to he revolved by the peiper as it passes over them, and the other or top the machine.

In washing end drying the paper it is drawn by the roller 24, assisted by the rerolling device, from the printer over the roller 29, under the roller 28 Without engaging it, where the flow of'weterfrom the spraypipe depresses the paper against the strips 27, where it is prevented from being drawn up egeiiist the roller 28 by the weight of the inner-roller5t is revolved by the ta es 60, driven bv a OFOSS-bfill; s1 item the s left of water, and the pe'per receives its first weterbath. The pep-er is dragged over said strips egaiiist the rollers 30, then behind the s ray- It will be seen that the priming-paper is unrolled endfed with the tracing through the printer where the tracing and said paper are separated, that the paper is fed from the printer forwoshing and dryiiig'in e eontinw ous strip or length which is rerolled with the prints, washed, dried, and finished.

it will be observed that the prints are washed by applying water only to one side of the paper, that the paper is dragged" through an accumulation of water fm'mthe 3 may on the paper and as it passes-fiiei'el f one is further washed and cleansed by' the colptinuous flow of water thereon from the SP1 {Ly-pipe, th at the sprav-pipe Wipes the pa er of surplus water, so that the paper has I on \e dampened print-surface who it leeves the p pe, that while one portion of hg oper 25 and a device to swear is being washed other portions of the paper are dried anduerolled, and that by this system the back 01 reverse side of the paper is prevented from becoming wet.
